What's New

The major updates to this guide, newest first. Smaller polish — navigation tweaks, mobile layout, search and SEO — happens continuously and isn't tracked here.

2026-05-13 — 2026 roadmap deep-dives

Eight new senior-level topics filling gaps against a 2026 .NET roadmap: the architectural style trio (Monolith, Modular Monolith, Microservices), legacy modernization (Strangler-Fig & Sidecar, Refactoring Legacy Codebases, When NOT to Apply a Pattern), security depth (Keycloak, Refresh Token Rotation & Revocation), and platform breadth (AWS for .NET, Dapr for .NET). A new tag chip flags each — it rotates away when the next batch lands.

2026-05-11 — Cloud & DevOps: first-principles concepts

Every topic in Cloud & DevOps (Docker, Kubernetes, Container Apps & AKS, Azure Storage, Cosmos DB, Redis, Service Bus, Event Hubs, App Configuration, Key Vault, Azure Monitor, Bicep, Terraform, CI/CD, Feature Flags, and more — 29 topics in all) now opens with a "What X is" explanation and an ASCII diagram before any code or commands. You can answer "what is a container?" or "why does this partition key choice matter?" from the page itself, without chasing external links. Roughly 1,000 new lines of conceptual material across the section.

2026-05-05 — Bookmarks

Tap the bookmark icon at the top-right of any topic to save it for later. Bookmarks live in your browser only — no account, no login, no tracking. A dedicated Bookmarks page lists everything you've saved.

2026-05-01 — Glossary upgrade

The Glossary now has an A–Z jump bar at the top so you can navigate to the term you want in one tap. Every abbreviation across the corpus (CQRS, gRPC, OTel, RPS, and more) auto-expands as a tooltip on hover, sourced from a single shared file — definitions stay consistent across every topic.

2026-04-30 — Major content build-out

The guide reached its target shape: ~240 topics across 19 sections, every topic following the same 10-part template (Key Points → Concepts → Code: correct vs wrong → Patterns → Trade-offs → When to use & when to avoid → Interview Q&A → Gotchas → Further reading). Highlights:

  • AI / LLM Integration — 24 topics covering Microsoft.Extensions.AI, the Agent Framework, Model Context Protocol, RAG and vector stores, local & edge inference, Azure OpenAI / Foundry, and AI security & observability.
  • System Design — 6 end-to-end case studies (high-throughput public API, event-driven order pipeline, multi-tenant SaaS, real-time collaboration app, batch processing pipeline, RAG app on .NET).
  • Distributed Systems, Observability, Security, and Data Access filled out with senior-interview coverage.

2026-04-28 — Initial release

The guide launched as a senior .NET full-stack study guide built on MkDocs Material and hosted on Azure Static Web Apps. The initial corpus covered runtime / CLR, ASP.NET Core, data access, distributed systems, observability, security, performance, testing, and DevOps fundamentals.
